Secrets are part of the everyday in the spy world, but that doesn't mean they don't create problems in relationships. Those in the business understand the need to keep details classified, yet they can also be the most suspicious. On tonight's Covert Affairs, "Embassy Row," trusts will be broken.

The ability to keep a secret is helping Auggie at the moment with both Hayley and Natasha in his life. In last week's episode, he was able to keep them both satisfied with a simple, "It's work" response. That likely won't hold up for much longer.

With his own relationship complications, Auggie gets pulled into Joan and Arthur's marriage when his boss makes a personal request. She wants to know what Arthur was doing in the Middle East.

Arthur hurt his shoulder and instead of taking his response at face value, Joan's determined to find out where he was and what he was doing. Will Auggie help her?
